Asphalt and Automotive Undercoatings

Polybutene is used as a plasticiser for the asphalt compounds. The typical applications include automobile undercoatings, rubber sheets, and electrical insulation of the asphalt compounds. When used in undercoating applications in automotive, it prevents corrosion, provides excellent vibration isolation and prevents cracking and breakage of the asphalt/rubber sheet due to the following properties:

  • Polybutene extends the life-cycle of the asphalt compound.
  • has excellent low temperature flexural properties.
  • Improves tensile strength.
  • Has good low-temperature resistance.
  • Has good dampening properties.
